Application October 20, 1945, Serial No. 623,519

1 'Claim.

' The present invention relates to containers for oil, gasoline and the like and particularly to improvements in pouring spouts for such containers.

It is the object of my invention to provide a device which is attachable to such containers and which includes a pouring spout normally seated within the containen'but which may be projected therefrom for pouring purposes.

Another object is to provide means for limiting the sliding movement of the spout in and out of the container to the end that it may not become detached from the parts of the device associated therewith. Still another object is to provide means for locking the spout tightly in projected position so as to make certain that no leakage can take place during the pouring operations.

Further objects and the many advantageous features of the invention will be best understood from the following detailed description thereof and by referring to the accompanying drawings, of which:

Fig. 1 is a plan view of a retractable pouring spout attachment for a container and with parts thereof broken away for the sake of clearness;

Fig. 2 is a substantially corresponding side elevational view showing the device in its relation to a container to which it is attached;

Fig. 3 is a similar view illustrating a slightly modified form of the invention; and

Fig. 4 shows details of construction the importance of which is hereinafter fully explained.

Oil and gasoline containers are generally fitted at the top with a flange which may be internally or externally threaded to receive a screw cap. The device of my invention is, in Fig. 2, shown attached to such an internally threaded container flange A, and it comprises a shouldered plug I, which is made with screw threads engaging the threads of the container flange to close the entrance to the container.

This plug is shown recessed at 2, and the bottom thereof is perforated to receive therein a pouring spout 3. It is noticed that a flange 4 rises from the bottom of the recess and that this flange is internally threaded at 5 to receive a threaded shoulder 6 which, in turn, is fastened to the lower end ofthe spout 3. It is also to be noted that the upper end of the spout is fitted with a shoulder 1. These two shoulders limit the projecting and retracting movements of the spout within the plug and so prevent detachment of the spout therefrom.

The flange 4 is also made with external screw threads 8 of a size to receive a closure member 9 at the bottom of the recess 2 to form therein a seat for the closure member. It is to be noted that the face of this gasket is slanting and this is done in order to make certain that the tapering lower edge of the closure member becomes sufficiently embedded therein to insure a tight joint, see also Fig. 4. It is also advisable to place a gasket l l between the plug and the face of the container flange to provide a leak proof joint at this point.

When it is desired todischarge liquid from the container, it is merely required to unscrew the closure member 9 and to draw the spout out of the plug until it is arrested by the threaded shoulder 6, whereupon a few turns of the spout causes the threads of the shoulder to enter and to seat within the threads 5 thereby to lock the spout firmly and tightly in this position.

The spout should be made flexible for convenient pouring, and a vent pipe i2 should be seated in the bottom of the recess 2 in order to insure smooth and uninterrupted discharge from the container.

As above stated, some containers are made with an externally threaded flange, and such structure is illustrated in Fig. 3. The device of my invention may be as readily attached to the internally threaded flange B of this modified container by merely drawing, spinning or otherwise forming the top flange 2i} thereof downward, substantially as indicated in this drawing, and by providing therein screw threads to match the threads of the container flange. It is also in this case required to place a gasket 2! on the container at the bottom of the flange thereof in order to provide a tight joint. In all other respects, the device of the invention may remain as above described and will function in the same manner.

I claim:

For use on a container having at the top thereof a flanged opening provided with screw threads, a threaded plug engaging the screw threads of the container flange to close the opening therethrough, said plug having a circular recess sunk in the upper surface thereof and a concentric tubular flange rising from the bottom of said recess to provide therethrough a discharge opening for the container, the upper portion of said tubular flange and the lower portion of the opening therethrough being provided with screw threads, a. pouring spout slidably fitted in said opening and having top and bottom shoulders for limiting movement thereof in the opening of the plug flange, the lower shoulder thereof having screw threads for engaging the threads of the plug flange to lock the spout in extended position in said flange, the bottom of the plug recess having a smaller threaded aperture therethrough, and a vent pipe having screw threads engaging the threads of said aperture and downwardly extending therefrom.
